Bessemer Gas Intake
The converter's air intake.
The Bessemer Gas Intake is the converter's air port, and it has to face the same way as the Bessemer Control: any other orientation completes the structure and then refuses to run, with "Gas intake misaligned!" on the panel. It is a fixed port rather than a pipe node, so a pipe has to sit in the cell in front of it, presenting a connector back at it. See Bessemer process for the 2.5 atm gate it has to clear before the vessel does anything at all.
